Star Trek tricorder-style heart rate monitor

A heart rate monitor can be an important tool for tracking fitness and exertion levels, but what if you want something a bit more interesting style-wise? For a novel idea, be sure to check out the project shown below from “Taste The Code.”

In it, Blagojce Kolicoski turns a handle used for launching rotating toys into something reminiscent of a tricorder from Star Trek.

The build stuffs an Arduino, a pulse sensor, and a tiny OLED display into the handle, which conveniently already had accommodations for three AA batteries. This, along with the monitor’s I2C connection, meant that wiring everything up was quite simple.
